All T tail transports look to have massive tails.
And I like how you can infer all of that with a glance at a photo, maybe all aerospace companies should hire you to give their designs a once over seeing as you seem to know whether a plane will fly the way they want via eyeballing.
yes picture are enough. its fate will be worst among the wider fuselage aircraft. See A400M, A380, C-2, An-70, An-124 relaunch. All these aircraft has significant difficulty in keeping cost down and keep production number high per year with relatively long certification process. Only C-17 was developed in low inflationary period of 1990s with stable multi decade orders. and there is not much use of C-17 beyond tranpsort. There is no high power AWACS and tanker version in wide use.
In case you didn’t read my post, the end point was that Y-20 probably won’t be challenging Il-476 for export orders any time soon. So I’m not sure why you’re suddenly so testy.
Y-20 cannot compete in Chinese domestic market as its engines are obsolete and airframe is cannot be certified in reasonable time. like in 3 to 4 years.

Btw Y-20s seemingly unwieldy tail is likely an effect of angle and the generally low resolution of the picture.
From the same angle and distance. the tail is exceedingly large. and engines look exeedingly small. Its dysfunctional design.
We haven’t got a decent side picture yet, and this CG is the closest thing we got (most likely made by someone who was actually there to give us a teasuer of the eventual real high res photos that inevitably must have been taken)
If this is accurate at all clearly its tail is not as large as you believe, at least it looks proportionally sized with the likes of C-17, Il-76 and A400M (not to mention C-2, which also has a massive tail)
The point is that this design is not so much multifuctional. it will likely have much lower speed and altitude. I highly doubt it has crusing speed anywhere close to 850km/hr. and with lower procurement per year. It will never achieve economies of scale for sustainable operations.
ilyushin was nice plane but 1970s is over. better to use a fresh design than something with 40 year old inspiration.
There is nothing new in Y-20 but amalgamation of various designs. Nose Wings, oversize tail seems to me inspired from Antonov.
Fortunately for the Russians, it will be a while before Y-20 finishes testing, not to mention the new high bypass WS-10, (I doubt the Russians will allow Y-20 to be exported with their engines) as well as the (hopefully) large order of this plane which the PLA places with hXAC probably unable to keep up a high production rate for both internal and external demand.
But in terms of the maximum achievable performance for Y-20 in the most important aspect for transporters (carrying capacity), it appears that it’s fuselage is larger and wider than that of Il-76 and engines for the moment will be the only limitation
have u looked at the tail of plane. It looks bigger than the plane. I can predict the plane will end up to be overweight/draggrier/low operational speed & altitude with short life span and will unable to fullfill most of mission requirements.
and IL-476 has delivery schedule of 103 planes before 2021. Not orders.
